Magnifico by Victoria Miles

All 11-year-old Mariangela wants is to learn how to play the piano. But one day when she comes home from school, she finds her grandfather’s old accordion instead. Although Mariangela tries to learn how to play the accordion at her music lessons, it’s hard – and she’s pretty horrible! Not only that, but she has to lug the accordion through her neighbourhood so that everyone can see, especially the school bully, who makes fun of her every time she passes.
Join Mariangela and her two best friends, Esther and Dot, as they explore different cultures in their neighbourhood of Strathcona, Vancouver. As Mariangela struggles to master (and avoid playing) the accordion, she ends up learning about her family’s history and culture as they made their way to Canada from Italy. She even learns a little bit about herself along the way.
